  no-one has yet developed an entirely convincing theoretical
  explanation for why regularization helps networks generalize. Indeed,
  researchers continue to write papers where they try different
  approaches to regularization, compare them to see which works better,
  and attempt to understand why different approaches work better or
  worse. And so you can view regularization as something of a kludge.
  While it often helps, we don't have an entirely satisfactory
  systematic understanding of what's going on, merely incomplete
  heuristics and rules of thumb.

  There's a deeper set of issues here, issues which go to the heart of
  science. It's the question of how we generalize. Regularization may
  give us a computational magic wand that helps our networks generalize
  better, but it doesn't give us a principled understanding of how
  generalization works, nor of what the best approach is.
